IL-21 Analyte

Description - Interleukin-21 (IL-21) is a regulatory cytokine thought to play a role in the transition between innate and adaptive immunity. It is produced and secreted by a variety of CD4+ T cells, NK cells, and T follicular helper cells. IL 21 is a regulator in the production and proliferation of B cells, T cells, and NK cells. IL-21 activity is mediated by binding its receptor, IL-21R. IL-21 is a target of novel therapeutic approaches such as the use of IL 21 blockers to prevent inflammation and/or malignancy.

Disease Focus - Inflammatory diseases, including rheumatoid arthritis, collagen-induced arthritis, colitis-associated colon cancer, ulcerative colitis, and Crohn’s disease.

Application Area - Inflammation, cytokines and chemokines
